Question 1: A gram of radioactive material has a half life of x.
Homework Equations
Please not that this is a generally question and I am not actually solving for X.
After x amount of time, how much will be left?
The Attempt at a Solution
I believe the answer is...
Graphing a function on a given interval...??
My problem is: Use a graphing calculator to graph the function...?
...over the given interval f(x)= -x^4+3x^3-4x+3 (-2,3).
How do you graph something on a specific interval?
P.S. I have the Casio fx-9750G PLUS graphing calculator.
I am not getting the answer that my calculator is giving me for the following:
Find the following values for x^2-1 (all over) x+4
f(2a-1)
I am getting 4a^2 (all over) 2a+3 for my final answer and my calculator is getting (2a-1)^2-1 (all over) 2a+3.
What did I do wrong? Also, how do...
1.) How do you answer this?
Find the equation of the line that has a slope undefined and passes through the points (3, -4).
I got y=-4
------------------------
2.) Write the standard and general equations of the circle with radius 4 and center (1,2).
I got STANDARD: (x-1)^2 +...
I know the product, quotient, and chain rules. I get confused when I get to the something du= something dx. Now, I have to take that and put it in the original. Please explain that part. Is there like a formula or something for that part?
I understand that u is just another letter, but after you take the hardest part of the equation and find the derivative you have some du=dx. Now you must write that in the form of the equation. This is the part where I get stuck.
